Auth Engineer — Users & Auth

We're looking for an Auth Engineer to own, architect, and build the systems that define how users exist and move within Clara's platform — authentication, authorization, identity, and access control. This is one of those roles where the work is invisible when it's done right and critical when it's not. The scope is deep and end-to-end: architecting the identity layer, designing auth flows, managing the user lifecycle, integrating Auth0 with Clara's platform, and making sure the frontend and backend sides of identity speak the same language. You'll be the person the rest of engineering turns to when there's an auth question no one else can answer. Security isn't a checklist here — it's a first-class concern baked into how we build.
